eth_getBlockByHash

返回具有指定哈希的块。

参数

• DATA, 32字节 - 块哈希
• Boolean - 为true时返回完整的交易对象，否则仅返回交易哈希

params: [
   '0xe670ec64341771606e55d6b4ca35a1a6b75ee3d5145a99d05921026d1527331',
   true
]

返回值

• logsBloom: DATA, 256 Bytes - 快日志的bloom过滤器，挂起块为null
• transactionsRoot: DATA, 32 Bytes - 块中的交易树根节点
• stateRoot: DATA, 32 Bytes - 块最终状态树的根节点
• receiptsRoot: DATA, 32 Bytes - 块交易收据树的根节点
• miner: DATA, 20 Bytes - 挖矿奖励的接收账户
• difficulty: QUANTITY - 块难度，整数
• totalDifficulty: QUANTITY - 截止到本块的链上总难度
• extraData: DATA - 块额外数据
• size: QUANTITY - 本块字节数
• gasLimit: QUANTITY - 本块允许的最大gas用量
• gasUsed: QUANTITY - 本块中所有交易使用的总gas用量
• timestamp: QUANTITY - 块时间戳
• transactions: Array - 交易对象数组，或32字节长的交易哈希数组
• uncles: Array - 叔伯哈希数组
